IT — Teaser Trailer

Clowns are scary as hell -- that's a given. But a clown that came from the mind of Stephen King -- well, that's the stuff of your worst nightmares.

Check out the very first trailer for "IT," the highly anticipated big-screen adaptation of Stephen King's enormously popular 1986 horror novel about a demonic monster clown named Pennywise who terrorizes a group of childhood friends as they grow up in a small, suburban town in Maine.

Swedish actor Bill Skarsgard, the younger brother of Alexander and son of Stellan, who is perhaps best known for starring in Netflix's short-lived supernatural series "Hemlock Grove," portrays Pennywise in the upcoming film, which is directed by Argentine horror director Andres Muschietti, of "Mama" fame.

King's book was originally turned into a two-part TV miniseries in 1990, which became a cult favorite largely due to Tim Curry's terrifying yet unforgettable performance as Pennywise.

The film version of "IT" is due to hit theaters on September 8th.
